Bacterial DNA was extracted, and the V4 region of the 16s rRNA gene was amplified. PCR-generated amplicons were sequenced, and operational taxonomic units (OTUs) were classified using the Silva database. Shannon Diversity Indices (SDIs) were estimated, and alpha diversity differences were tested using ANOVA. Bray-Curtis indices were computed to estimate beta diversity across groups, and Principal Coordinate Analysis (PCoA) ordination was completed. Significant variations in microbiome structure across groups was assessed using PERMANOVA. Genera that were differentially abundant across groups (absolute log2 fold change &gt; 2) were identified.</p></div><div><h3>RESULTS</h3><p>OTUs clustered into three distinct groups based on sample source. PCoA results demonstrated statistically significant differences between clinical health and peri-implantitis (P-adjusted &lt; 0.05), between clinical health and periodontitis (P-adjusted &lt; 0.05), and between peri-implantitis and periodontitis (P-adjusted &lt; 0.05). Biofilms derived from cases of clinical health exhibited a mean SDI of 2.46. By comparison, mean SDIs in the peri-implantitis and periodontitis groups amounted to 3.023 (Padjusted &lt; 0.05) and 3.061 (P-adjusted &lt; 0.05), respectively.

Rather, disease results from true polymicrobial activity characterized by accumulation of specific genes, and thus functions, within the biofilm. Moreover, the pathogenesis of peri-implantitis is known to involve the presence of titanium particles that influence the inflammatory response.

These particular bacteria are important components in the process of caries formation, periodontal disease, and failed endodontic treatment.</p></div><div><h3>METHODS</h3><p>A search of Pubmed was conducted for peer-reviewed randomized control trials, clinical trials, and studies that were less than five years old. The keywords used to find relevant articles were: bacteria, oral bacteria, phage therapy, bacteriophage therapy, pathogenic bacteria, and dental bacteria.</p></div><div><h3>RESULTS</h3><p>The studies that were reviewed demonstrated phage therapy to be effective in reducing oral bacteria commonly responsible for dental caries, periodontal disease, and failed endodontic treatment. The first study showed the isolated phage, SMHBZ8, targeted S. mutans and reduced both biofilm formation and demineralization of enamel. The second study demonstrated the ability of a lysogenic bacteriophage, S1249, to be induced into the lytic cycle in human serum and effectively eliminate A. actinomycetemcomitans, a bacteria implicated in aggressive periodontal disease and known to be resistant to serum. The third study found a phage, PEf771, targeting E. faecalis in endodontically treated teeth with refractory periapical periodontitis was found to have greater substantivity and antibiotic properties than traditional medicaments used in root canal treatment.</p></div><div><h3>CONCLUSIONS</h3><p>These studies prove the viability of phage therapy as a treatment modality in targeting pathogens that contribute to major oral diseases.

Current treatment options for these oral diseases carry risks such as antibiotic resistance, staining, and toxicity. The ability of bacteriophage to target caries-causing bacteria such as S. mutans while sparing commensal bacteria is promising for preventive dentistry while the specificity and replicating abilities are desirable for eliminating periodontal and endodontic pathogens.

The model was modified to extract tooth #8 digitally in the Blue Sky Bio® software. Surgical guides were designed to extend from tooth number 6 to 10. Forty guides were printed with Formlabs Form 3B+ printer and Formlabs surgical guide resin following manufacturer's instructions. Each guide was scanned with Prime Scan optical scanner before disinfection and sterilization. Twenty guides were individually packaged, and autoclave sterilized at manufacturer's recommendation of 134°C for 20 minutes. The remaining twenty guides were soaked in 70% isopropyl alcohol for fifteen minutes. After sterilization and disinfection, the guides were scanned and STL files from pre- and post-sterilization were compared in GeoMagic Control X software to examine dimensional changes. A paired T-test was done to evaluate distortion of the guide before and after sterilization and disinfection. An unpaired T-test was done to compare the disinfection and sterilization test groups.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;RESULTS&lt;/h3&gt;&lt;p&gt;The average deviation at the lingual, incisal, buccal, combined surfaces, and the entire guide of the sterilized group was 6.28μm, -2.4μm, -20.6μm, 5.6μm, and 12.6μm respectively.

The b* parameter was most influenced, showing a trend towards yellowing (ordered as HS&gt;XT&gt;GS&gt;CP&gt;FT), followed by a decrease in the L* parameter indicating darkening (GS&gt;XT≥HS≥CP&gt;FT). Finally, the a* parameter experienced minor positive and negative variations.</p></div><div><h3>CONCLUSIONS</h3><p>Resin sealants demonstrate higher susceptibility to staining than flowable resin composites. Black tea exposure led to a more yellow hue (increased b*) and a darkening effect (reduced L*) in resin sealants.</p></div><div><h3>IMPLICATIONS</h3><p>Sealants are prone to color changes when exposed to the oral environment, more so than other composite materials or the tooth structure itself. Understanding how this color change occurs is crucial for accurately diagnosing a stained sealant rather than mistaking it for secondary caries. It is noteworthy that different sealants exhibit varying degrees of staining.</p></div>","PeriodicalId":100364,"journal":{"name":"Dentistry Review","volume":"4 3","pages":"Article 100118"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772559624000415/pdfft?md5=3878970a5ffc05f74723d77ce428db6e&pid=1-s2.0-S2772559624000415-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142169007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
